The echocardiographic findings in a patient with cardiogenic shock secondary to acute right ventricular myocardial infarction based on typical clinical, electrocardiographic, and hemodynamic features are described. The echocardiogram demonstrated a large RV/LV minor axis ratio caused by a volume overload of the right ventricle and an underfilled left ventricle. The interventricular septum showed abnormal movement, presumably due to right ventricular overload or severe disease of the left anterior descending coronary artery. Diminished septal systolic thickening, as seen in our patient, may be explained by extension of the infarct from the right ventricle to the adjacent part of the septum. Predominant right ventricular involvement can be a cause for a correctable hypotension in patients with acute myocardial infarction and should therefore be recognized early. The echocardiographic picture demonstrated in our patient, when considered in conjunction with the clinical status, can be useful for early diagnosis.
